On the Corrosion of Two Types of Bronzes Under Cavitation
Keywords:
cavitation, bronze, mass loss, gravimetric index
Abstract
This article contains the results of the experiments concerning the mass loss of two types of bronze in seawater in the cavitation produced by ultrasound generated by a high-frequency generator. The mass loss models are presented for the experimental conditions when the generator worked at different powers - 80 W, 120 W, and 180 W. In all scenarios, the results show that the bronze with Sn has the highest mass loss in the cavitation field.
